Use Of Duplicate Output - Panasonic FP7 Series Command Reference Manual

19.6 Use of Duplicate Output

■
Duplicate Output
● Duplicate output refers to repeatedly specifying the same output in a single sequence
program.
● If the same output is specified for the "OT" and "KP" instructions, it is considered to be
duplicate outputs.
● Even if the same output is used for other multiple instructions, such as SET, RST, or high-
level instructions (for example, data transfer), it is not regarded as duplicate outputs.
● Usually, an error occurs if the unit is switched to the RUN mode with duplicate outputs. The
ERROR LED goes ON and the self-diagnosis flag SR0 turns ON.
■
How to check for duplicate output
● You can check for duplicate outputs in a program using the tool software FPWIN GR7 in the
following method.
1. From the menu bar, select Debug>Project total check.
The "Project total check" dialog box is displayed.
2. Press the "Execute (E)" button.
If duplicate outputs are identified, the PB name, address, and error details (duplicate
outputs definition error) are displayed.
3. Select a given line and press the [Jump] button.
The cursor moves to the instruction where duplicate outputs are involved.
■
Enabling duplicate output
● If you need to use output repeatedly due to the content of the program, duplicate output can
be enabled.
● In such cases, switch CPU configuration>Select operation>Duplicate output
authorization to "ON".
● In this case, an error will not result even if the program is executed.
● Even when a project total check is conducted using the tool software FPWIN GR7, the
instruction used at the start is not indicated. Instead, the second and later outputs that are
regarded as duplicate use are indicated.
■
Processing of duplicate uses of the same output
● If the same coil is specified in instructions output to internal relays or output relays (for
example, the OT, KP, SET, RST and/or transfer instructions), contents thereof are rewritten at
each step during operation.
